From talkers to texters back to talkers
Suddenly, one gets up and moves to a seat about 15 feet away, whips out her cell phone, obviously composing a text message. She sends it. Looks up to her friend 15 feet away and waits for her reaction. Her friend looks at her phone and replies.
She had sent the text message to her friend 15 feet away!
This continues for about 5-10 minutes or so. They alternately exchange meaningful glances the whole time.
And then, toward the end of their train ride, they moved side by side again, and start TALKING! You know ... "talking"!
Please comment below on your theories of the nature of their text messages.
